使用 OpenXml 从内存中读取 WordprocessingDocument 并保存到 AddAlternativeFormatImportPart

Question

这项工作正常：

MemoryStream ms = //do some in memory on WordprocessingDocument ;
AlternativeFormatImportPart chunk = mainPart.AddAlternativeFormatImportPart(
                    AlternativeFormatImportPartType.WordprocessingML,
                    altChunkId);  
using(var fs = new FileStream(@"c:\\temp\\1.docx", FileMode.Create, FileAccess.ReadWrite,FileShare.Read))
        ms.WriteTo(fs);

using(FileStream fs = new FileStream(@"c:\\temp\\1.docx", FileMode.Open, FileAccess.Read))
        chunk.FeedData(fs);

无法正确从内存流 WordprocessingDocument 读取并使用 OpenXml 保存到另一个上的 AddAlternativeFormatImportPart 而不保存到光盘，

MemoryStream ms = //do some in memory on WordprocessingDocument ;
chunk.FeedData(fs);

怎么办？

这对我有帮助

MemoryStream ms = //do some in memory on WordprocessingDocument ;
ms.Seek(0, SeekOrigin.Begin);
chunk.FeedData(ms);
